ELECTRIC SWITCH.

Application fi-IedJune 25, lacs. Serial No. scenes.

fication.

The object of the invention is to produce a switchhaving features of novelty and advantage and particularly to produce a switch which may be operated by a doorbolt.

In the drawingsFigure 1 is an outside end view of a switch embodying my invention. Fig. 2 is a side. view of the same;

Fig. 3 is a bottom view of the same. Fig st is a top view of the same. gig. 5 shows the manner of installing the-sivi ch for use.

The invention will be described as embodied in a switch of the push-button type. The switch parts. are of usual construction with the exception that the off push-but ton is not connected directly with the switch I but through mechanism which will be hereinatter described.

Referring to the drawings a denotes the usual receptacle made of porcelaiiror like material, 5 an electric switch mechanism whibh as shown is of the push-button type, c the on bushbutton, d the off pushbutton.

Mounted on the rear of the receptacle is a rock-shaft 1 having at one end a crank-arm 3. This crank-arm is connected by a link 4: with the on push-buttons. About this rock-shaft there is coiled a power spring 5, one end of which is secured to the shaft and the other end held against a fixed abutment so that when the shaft is rocked in one position by the on push-button, the spring will be wound up to store power for the further operation of the switch. On the side of the receptacle is secured a rock-arbor 10 secured to which is a catch 11 arranged in operative relation with the dog 6 on the rock shaft and adapted when the switch is set in the on position to interlock with said dog and hold the power spring under tension. This rock-arbor 10 is connected by the link 12 with the off push-button (Z. The catch 11 has a spring 13 tending to throw it into engagement with the dog, when such movement is possible, and the trip ltwhichis in the path of movement of the door bolt.

This switch is to be mounted in the face of the door casing. It is difficult to mount it near enough tothe edge of the casing so that the lock b'olt will come in direct contact with the trip, and while'this arrangement might be obtained when the switch is first installed, the shrinkage or settling of the building might soon separate theparts so that the lock bolt would not operate the trip. Consequently I set the switch alittle bitaway' from the edge of the casing and cut an opening through from the lock bolt recess to the recess in which the switch is Patented Aug.5;1;;9i3. a

mounted. In this recess thereis mounted a v telescoping bolt 20 held in its extended position by a spring 21 which is stiffer than the catch spring 13. This bolt forms the operative connection between the lock bolt and the trip. When the lock bolt is first thrown it movesl this connecting bolt, pressing the trip down and'disengaging the catch from I the dog. Further movement of the lock bolt will compress the spring 21 and telescope the connecting bolt.

The operation of the device is as follows: An; inward movement of the on button 0 throws the poles into position to bridge the stationary contacts a and light the lights. Through the link 4 this inward movement of the on push-button rotates the rock shaft 1, moving the dog under the catch untilsuch time as the catch is thrown down by the spring 13 into engagement with the dog. If it is desired tir put the lights out from the switch a pressureon-the cit push-bub ton rocks the rock-arbor 10, moving the catch out of-engagement with the dog. The spring 5, which is stronger than the switch spring, throws the rock-shaft back into normal position and through the crank-arm. 2

and the link 4 moves the switch parts to unlock the poles so that they may the thrown by the switch spring to break the circuit.f

Switches of this character are designed."

particularly for hotel use or in any case where it is desired to put out the lights in an apartment which has been vacated and.

locked. a n

An arrangement of location of thevarious no i parts can be changed from that shown and departing from the ed to operate said switch mechanism to close a circuit, a power device actuated and made operative by said push-button, means for holding said power device 1n operatlveposition, a second push-button connected with,

and adapted to release said holding means, and means independent of said push-buttons for releasing said holding'means;

2. Ina-n electricswitch the combination with the switch mechanism, and an operating arm extending therefrom, of a push-button connected directly with adapted to' operate the switch to close the circuit, a rocloshait, a crank-arm connection between said crank-arm and said push-button, a spring coiled about said shaft and having said arm and thereon, a

one end held by a fixed abutment, af dog 'on saidsha ft, a catch adapted to engage said dog, a trip on said catch whereby said catch may be disengaged from .the'dog, and a push-button connected with released to move said arm. in the opposite direction, means for holding said power denected with and made operative by the move- 'ment of said push-button and adapted when Vice in operative position comprising a catch, r

'a trip extending from said catch, a rockarbor on which saidrcatch 1s vmounted, a, spring exerting pressure on said catch to cause it to engage saidpower device, a second push-button and a connection between it and I said rock-arbor.
